I chose to go a cleanse diet, the Master Cleanse (Beyonce did it) to support a friend doing it who wanted to lose weight before an event. I was quite overweight at the time and had been suffering from depression for a couple of years. I had massive headaches for the first four days of the cleanse, and then all of a sudden it was like a cloud lifted and I was myself again. I did lose weight as well, 15 pounds in ten days, but what the cleanse did for me is give me a chance to begin a healthy lifestyle, a clean slate so-to-speak. It's not for everyone (my friend quit after eight days, she felt weak and sick) but as for me, doing a cleanse diet, even though it was extreme, gave me my life back. Just be safe (and if you're doing one that's similar to a fast, make sure to BREAK IT PROPERLY or you could really hurt yourself) and don't expect it to change you. Only you can do that.

My fiance and I did the Wild Rose Cleanse and it was a breakthrough for me. We are pretty healthy as it is, being vegetarian, non-smoking, non-drinking, so the diet wasn't a huge stretch. The hardest thing was cutting out sugar for twelve days since I have a huge sweet tooth.
Also, I was concerned about keeping my energy levels up high enough to continue my twice daily workouts.
Well, I was able to work out the entire twelve days and by the time I passed day three the sugar toxins were out of my body. I relalized how scary it was the my body was so dependant on energy sources such as sugar and caffeine to keep it going that despite the fact the cleanse diet was providing all the calories and nutrients I needed, I still had a tough time those first few days. It was a real wake up call.
Since completing the cleanse, I have stuck to no sugar/gluten/dairy as much as possible in my daily life and I know my health has benefited from it.
Prior to the cleanse, I could not remember a day in the last three years when I did not have severe digestion issues. Since the cleanse, my systems are all "go" and I feel great!
People need to remember - Cleanses are not about quick fixes for weight loss, they are triggers for lifestyle changes that will improve your total body health over the LONG TERM. Results and side effects are directly related to what you lifestyle was prior to the clease - if your body is full of toxins (eg. sugar, alcohol, nicotine) you will probably have a tough go of it as everything "unloads" from your body systems. I think these cleanses are good tools for demonstrating the power chemicals and additives have over our bodies, and how we need to break those chains in order to life a healthier life!
It just makes you more "aware".
